Jack Fruit is not so popular in Kenya, its fruit chunks are cooked, flesh used in fruit juice, salads, soup or made into pickles. Seeds are boiled or roasted and eaten as nuts.
Altitude: 400-1200m above sea level
Rainfall: 850-1500m p.a
Soil: rich, deep soil of medium texture
Clear bushes and tree stumps, remove perennial weeds. Dig holes 1m by 1m 1m at a spacing of 8m or 10m four weeks before planting. Keep the holes open for 2wks and then add 20kg well decomposed organic manure.
The crop can be propagated using seeds or seedlings raised on nursery. Dried and seeds stored more than one month will not germinate. The seedlings can be grafted or budded.
This calls for fresh and clean seeds. The seeds will take 3-8 weeks to germinate.
Establish nursery near water source and under shade. Sow seeds in line, 30 cm apart. Harden the seedlings to adapt to the conditions prevailing in the main field by reducing watering intervals and removing shade.
Done after 1.5 years for grafted seedlings at a spacing of 8m by 8m for grafted plants, 12m by 12m for un-grafted plants with other crops and around homestead 10m by 10m.
Water the plants immediately after transplanting. Apply 1-3kg of NPK per tree twice a year or alternatively 12kg manure combined with 200g CAN and 400 TSP per tree annually.
Make cuts on the bark or the stem, care should be taken when doing so as many openings may create route for secondary infections.
Birds– Most common are the mouse birds, can be controlled through fruit bagging.
Shoot borer caterpillar-Wet the affected parts, bagging of fruits and appropriate pesticides can be used sparingly.
Done 8-10 months after planting if trees raised from seeds. Yield is about 250 fruits per tree annually.
NB:There is need for all crops awareness to farmers as some crops remain Greek to many, this tells that the information flow in the agricultural sector has some gaps that must be filled.
